How to Root U.S. and Canada Galaxy S3 AT&T, T-Mobile, Sprint/US Ceullar! [Fail-Proof][Noob-Proof]

So, you want to root your U.S. or Canadian Galaxy S3 with the Qualcomm dual-core 1.5Ghz CPU?

UPDATE: Please see updated root method here instead!

If your Galaxy S3 model started with SGH-T999, SGH-I747, or SPH-L710, you can follow this step-by-step guide and root your phone within about 5 minutes.  No, this will not erase any apps or settings on your phone and does not affect your phone in any way other than install ClockworkMod Recovery and give you root.  (So if you have problems after rooting, don’t just assume it’s from rooting, it’s not.)

redruM ROM for Rooted T-Mobile/AT&T/Sprint Galaxy S3! [SGH-T999][SGH-I747][SPH-L710]

I know a lot of you have been waiting eagerly for T-Mobile Galaxy S3 ROMs and well, here’s my first T-Mobile Galaxy S3 ROM I’ve tried (and not that many out there right now) and glad to say I can recommend this one over the stock ROM. The redruM ROM also works on AT&T Galaxy S3 according to the author (in fact works for any Galaxy S3 with SIM but DO NOT TRY ON GT-i9300!!!). Also there’s a ported Sprint version you can try if you have a Sprint Galaxy S3.
